The application discloses a multifunctional analog instrument acquisition card based on a ZYNQ-7000
chip and a
data processing method. The acquisition card takes a ZYNQ-7000 series main control
chip as a core, a PS end is responsible for data storage and network transmission, and a PL end covers
data acquisition, output and cache modules. Four-way single-channel ADC circuits are adopted for
data acquisition, and the data is transmitted to the PS end by DMA after FIFO cache and conversion; a
signal output module generates analog signals according to instructions of an upper computer;
data transmission is realized by multi-channel DMA to be high-speed and stable; and an
Ethernet module guarantees communication with the upper computer. The application utilizes the unique structure of the ZYNQ
chip, and combines with the collaborative operation of various functional modules, has the advantages of modularization, high precision, high-speed
processing and
scalability, effectively solves many defects of existing
data acquisition systems, can be widely applied to
analog signal acquisition and
processing in many fields, improves the efficiency and precision of data acquisition and
processing, and has a great market application prospect.
